linear equations and problem solving

[dat_atx_chick]

ok so im having trouble with linear equations and problem solving....

i just dont get it......like this problem

you and your friend are each driving 379 miles from los angeles to san francisco. your friend leaves first, driving 52 miles per hour. she is 32 miles from los angeles when you leave,driving 60 miles per hour. how far do each of you drive before you are side by side???? :?:


so yeah if someone could help me out i'd really appreciate it....

Your friend has 32 mile headstart. distance = rate*time

So, they have travelled 32+52t miles when you have travelled 60t miles.

32+52t=60t, solve for t.
